Fuel vapor control system |
摘要 |
An electrically controlled vacuum operated valve controls flow of fuel vapors from a collector canister to the engine intake manifold. A pressure regulator controls fuel vapor flow from the canister to the inlet of the electric valve and is normally closed. During engine operation, if the control valve maintains a threshold level of vacuum at the regulator outlet, the regulator will permit fuel vapor flow from the canister to the control valve, otherwise the regulator is closed.
